My Favorite Realism & more – Ep.19 Oil Painting Q&A with Mark Carder

If you have a question for me, post it in the comments below. I'll answer as many as I can in the next episode. Here are links to each question answered in this video:
00:04 — a close look at some of my favorite realist paintings by artists like Arthur Streeton, James Jebusa Shannon, and more
13:53 — What type of brushes and how many brushes do I need to start portrait painting?
14:54 — I know you can generally mix any color with a limited palette like the Geneva Essential Palette, but would you discourage mixing Geneva paints with other brands? For example, can I use a pre-mixed tube of Payne's Gray?
15:48 — Can I use baby oil as a brush dip?
17:35 — What do you think about studying anatomy to help with illustrating a particular scene?
18:38 — If I am using Geneva paints, what medium should I use to adhere to the "fat over lean" rule?
20:16 — Cadmium Yellow is so costly. Why not use lemon yellow or something similar?
21:46 — Do you think certain colors are easier to paint than others? I find it hard to see details when painting really dark colors and even more when trying to add highlights to dark colors.
